If you want to find out more about Dianetics and Scientology, the best way to do this is to read an L. Ron Hubbard book on the subject. I personally recommend you read Science of Survival.
This book addresses exactly what it says - The science of survival. Everyday we encounter people who are kind, mean, loving, cruel, ad infinitum. This book gives you the tools to be able to tell who and what type of person you are dealing with before you get in over your head. Learn who to trust and who not to turn your back on before you get into trouble.
